    The ground resistance of each pin of the ATX power supply Ensure that the motherboard power supply is not short-circuited to the ground to prevent the expansion and extension of the motherboard failure Orange 3.3V Red 5V resistance to ground is about 200~500 Yellow 12V resistance is slightly larger than 3.3V and 5V White -5V Blue-12V resistance to ground is generally infinite Green 14 or 16 General boot control pin 600 or so, when it is about 1000~1500, check whether the circuit is protected or not The circuit “infinity” 1 means that the line is broken (ASUS Gigabyte motherboard 14-pin is particularly easy to break the line) Purple 9-pin standby 5V 500 or so Gray 8-pin PG signal is about 600. Infinity “1” should follow the line to see if it is an empty foot (now many boards are empty)
